BOEING-MACHINE.

Specification of Letters Patent.

"atented Oct. 8, 1912.

Application filed September 1, 1911. Serial No. 647,194.

To all coho m, it may concern Be it known that I, VIILBUR R. S'ronoiss, a citizen of the United States. and a resident of Arcadia, in the county oi. (hfawiord, State of Kansas, have invented a new and useful Improvement in Hoeing-hilachines, of which the following is a specification.

My invention is an improvement in hoeing machines, and has for its object the provision of a simple, easily operated and economical machine of the character specified, wherein mechanism is provided :for hoeing and thinning of plants in a manner closely resembling the thorough ope 'ation of hand working.

In the drawings :Figure 1 is a side view of the improvement, Fig. 2 is a plan view, Fig. 3 is a side view of the thinning wheel, and Fig. t is a section on the line 4lt of Fig. 1.

In the present embodiment of the inven tion, spaced alined spindles l and 1 are provided, and a frame consisting of spaced sleeves 2 connected by substantially U shaped portions 3 and 3 is suppm'ted by the spindles, each sleeve being 'joi'irnaltal on a spindle. The U-shaped portion 3 extends rearwardly from the sleeves and the portion 3 extends upwardly, and a lilearing 1 is journaled on the said portion 3, the bearing be,- ing secured to a tongue 5 near the rear end thereof. The tongue is provided with a yoke-shaped doubletree 6, the body of the said doubletree being pivoted. at 7 to the tongue, while the arms 8 thereof? have each connected therewith a swingletree 9.

A wheel 10 is 'journaled on each of the spindles, and is held in place by a linch pin 11, and the wheel on the spindle it is connected to the spindle by the pawl and ratchet mechanism shown in Fig. 4. The said mechanism comprises pawls 12 pivoted within the hub 13 of the wheel, and the said pa'wls are pressed by springs 14, into engagement with the ratchet wheel 15 secured to the spindle '1. The arrangement such that as long as the wheel is moved :torwardly the axle 1 will be turned therewith. When however. the wheels move rearwardly, the pawls will slip idly over the ratchet wheels.

The arms 8 oil? the donbletree are connected by rod 16, and brace rods 17 are arranged between the rod and the tongue. Other brace rods 18 are connected at one end to the rod, and at the other to ears 19 on the outer ends of the sleeves 2. Each of the sleeves 2 is provided with a vertical bearing 20 at ap- ]')1'()XlIlltll tl Y its center, and a bolt 21 is journaled in each oi the said bearings. A yoke consisting of a body 23 and arms 31- is connected with the bolt 2!, the arms being arranged at each end oil. the bearing 90, and having openings through which extends the bolt 21.. A plow beam 22 has one end inserted in the body of each yoke and is mired in place by means of bolts 25. A box 26 is secured to the rear end of each beam by means of a bolt 27, and each box has secured thereto a cross head 28. A guide 99 is provided at each end oi the cross head and the shank 30 of a cultivating plow is received in each guide 29 and is secured in place by bolts or screws 31. Each shank is provided with a reversible plow point 32, and one of the plows is set ahead of the other. Each box is provided with upwardly extending spaced cars 83, and a' handle 3 1- is pivoted betwcen the ears of each box. A link connects each cross head with the adjacent sleeve, one end of the link being pivoted to the sleeve at 36, while the other end is secured to the cross head. A rod 37 is connected with each of the sleeves near the vertical bearing 90. and the other end of each rod is connected with one end of a spiral spring 538, whose other end is (unmet-ted to a rod 39 secured to the rod 16, before mentioned.

The above described mechanism is the cultivating mechanism, and a cotton chopping device or thinning device is arranged between the plows. lhe said device comprises a yoke consisting of a body {l0 and spaced arms 41 the body having a bearing 10 journaled on the lower end of a shaft 43. The shaft 43 is journaled in bearings 42 secured on the inner end oi one of the cross heads 28, and the bearing is held in place on the shaft by means of nuts 44-, (Fig. 3).

A stub shaft 45 is journaled in bca rings 4-6 at the ends of the arms 41 of the yoke, and a chopping wheel or disk 4L7 is secured to the said shaft 45. The chopping wheel as shown in 3 is provided with spaced substantially radial cuts 4-8, dividing the periphtia'al surface of the disk into a pinrality of blades 4.). Each of the said blades is bent laterally with respect to the plane of the disk as indicated in Fig. 9, and the inner end oi the shaft to is connected to a shaft 50, by means ot a universal joint 51. The opposite end of the shaft is connected to a stub shaft 52 by means of a universal joint 58, the said shaft 52 being journaled in the U-shaped portion 3 of the frame. The forward end of the shaft 52 is provided with a bevel pinion 5A which meshes with a bevel gear wheel 55 on the inner end of the spindle 1 It will be evident that when the frame is drawn through the field, the chopping wheel or disk will be rotated, and each of the blades 49 will remove a portion of the plants in the row, thus thinning the row to the proper number of plants, while at the same time the plows 32 will thoroughly stir and cultivate the ground on each side of the row.

It will be noticed that each of the blades 4-9 is pointed at its front end at 56, that is, at the end which first engages the ground, and the inclination of all of the blades with respect to the plane of the disk is the same. i

I claim 1. A machine of the character specified, comprising a frame, wheels for supporting the frame, a plow beam connected with the. frame at each side thereof, a plurality of. plows supported by each beam, a cutting device for thinning the plants connected with one of the beams, said device comprising a yoke consisting of a body and spaced arms inclined with respect to the body, means for adjustably connecting the yoke body to the beam, a stub shaft journaled in the ends of the arms, a cutting wheel on the shaft between the arms, and a driving connection between one end of the shaft and a wheel, the cutting wheel comprising a disk having spaced substantially radial slots dividing the periphery of the disk into a plurality of blades, each blade having a point at one end, the said blades being inclined in the same direction with respect to the plane of the disk.

2. A machine of the character specified, comprising a frame, wheels for supporting the frame, a plow beam connected with the frame at each side thereof, a plurality of plows supported by each beam, a cutting device for thinning the plants connected with one of the beams, said device comprising a yoke consisting of a body and spaced arms inclined with respect to the body, means for adjustably connecting the yoke body to the beam, a stub shaft journaled in the ends of the arms, a cutting wheel on the shaft between the arms, and a driving connection between one end of the shaft and a wheel, the cutting wheel comprising a disk having spaced substantially radial slots dividing the periphery of the disk into a plu rality of blades.

3. A machine of the character specified, comprising a frame, wheels for supporting the frame, a plow beam connected with the frame at each side thereof, a plurality of plows supported by each beam, a cutting device fo-r thinning the plants connected with one of the beams, said device comprising a yoke consisting of a body and spaced arms inclined with respect to the body, means for adjustably connecting the yoke body to the beam, a disk journaled between the arms, and a driving connection between the disks and one of the wheels, said disk having a plurality of substantially radial'slot-s divide ing the periphery thereof into a plurality of blades.

4. A machine of the character specified, comprising a frame, wheels for supporting the frame, a plow beam connected with the frame at each side thereof, a plurality of plows supported by each beam, a cutting device for thinning the plants connected with one of the beams, said device comprising a yoke consisting of a body and spaced arm's inclined with respect to the body, and means for adjustably connecting the yoke body to the beam.
